Specific embodiment
As shown in Figure 1, tentatively lifting and being fixed in part to be processed hole by lathe first, make machine tool spindle and quilt It is unanimous on the whole and fixed to process axially bored line.
Then datum axis is established.The datum axis establishment method of machine tool chief axis is by displacement sensor Scanning Detction What deep hole blind hole surface was realized: detection, acquisition data, analysis and the reason for calculating deep hole blind hole are scanned to deep hole blind hole surface Think axial location, and calculates the deviation of current machine tool chief axis axial location and ideal position.
After datum axis determines, carries out machining tool main spindle's and detect automatically.By taking method shown in FIG. 1 as an example, use Laser displacement sensor (6) is scanned detection to the detection of deep hole blind hole surface location, can pass through numerical control radial tool post first (14) radial position of appropriate adjustment laser displacement sensor (6)；Secondly, using boring bar assembly (15) main shaft rotary motion and The axial feed motion of axis feeding knife rest (5), to processed bore area Scanning Detction, acquisition data；Then, blind to deep hole Hole surface acquisition data are analyzed and are calculated, and are obtained deep hole blind hole ideal axis position, are calculated current machine tool chief axis axis position It sets and the deviation of ideal position.
After obtaining machine tool chief axis and ideal position deviation size and Orientation, implement main spindle's adjust automatically, positioning.It carries out First successive step: operating deep hole blind hole and process, first determine whether main shaft bottom position is correct, if it exists deviation, drives bottom The four-axle linked adjustment control mechanism of portion's bearing support (16) corrects deviation；Then judge whether spindle top position is correct, if There are deviation, the four-axle linked adjustment control mechanism of driving top spherical bearing support (10) corrects deviation.After the completion, according to It needs, carries out detection and the judgement automatically again of machine tool chief axis position.
After the completion of machine tool chief axis is detected automatically, is adjusted, positioning, debugging, maintenance, processing, repairing, the inspection of implementable components The operations such as survey.
